Macbook chimes on start up but has black screen
My older white Macbook from about 2008 (serial # YD8110ULZ63) does not have a functioning monitor and I could use some help trouble shooting.
When pressing the power button in the top right hand corner to boot the machine up I get the usual chimes sound and the blueish light facing me on the right hand corner of the Macbook keyboard body lights up. The light stays on for a second and sometimes I get a grey screen for a beat, but more often the screen remains black. That same little light on the right corner below the keyboard goes out. If I close the screen (close the clam shell) that same little light comes back and pulses normally.
Some trouble shooting I have done:
I have reset the SMC as well as NVRAM/PRAM.
I booted up my sick Macbook as a Firewire drive and the hard drive showed up as an icon and I was able to access data.
I tried the DVI output on the side of my Macbook to see if I could use an known working external monitor. No signal was detected.
Anyone have any thoughts what my next steps to trouble shoot this problem might be? Or is there a possibility I have given enough information that someone can say what the likely problem is?
